The main reason that Mercury has no moons is due to the giant living next door - the sun. The sun is so much larger than Mercury that its gravity completely overwhelms any pull that the little planet itself has, and any material that might have become a moon gets gobbled up by the sun instead. Mars, on the other hand, is farther away from the sun, and does not have that powerful gravitational pull affecting it as strongly. When the material that formed Phobos and Deimos came along, it was pulled in by Mars' gravity and took up orbit there.
